Whoosh when under boost.. No power..

Wife and i went out tonight, and the drive home was a little spirited. Took some back roads and got on it a little. While i was winding down to cool off the engine a bit, i noticed that the turbo sounded louder than normal. Whenever i built boost, it made a loud whoosh, but there was no power behind it. I'm assuming its a boost leak.. But i don't see anything loose. Its a base 12 wrx, stock.
im sure i shouldn't drive it in for service..
Any input would be appreciated.. I would like to know what's up before i bring it in.
Sorry if i left out any details.. It just happened and I'm pretty bummed out.

Welcome to owning a turbo car. You probably have a major boost leak. Maybe your BPV failed and just leaks out all your boosties. Without logs and anything being obviously loose, it's really hard to tell. I'd take it in for service, it's still under warranty right?

Take it to the dealer but if I had to guess I'd say you blew the hose connecting the intercooler to the throttlebody off. To fix you have to take the intercooler off, put the hose back on the throttlebody and tighten the worm clam down. Very common problem on 08+

Yeah, its under warranty.. Its only a year old with about 3300 miles.
I'll pull the IC wheni get home from work and see what i can see.
I that gets me no where I'll get it to the dealer. My only question about that would be to have it towed, or is it safe to drive?

Maus has made a rare appearance by actually posting instead of just sitting in chat...and he's right.

I, along with many other 3rd gen owners, have had the same issue. If you google "throttle body intercooler leak wrx" you'll find many threads on the internets about this issue, including some DIY ways to fix it "better." I elected to have the dealership fix it whilst still under warranty, but if it happens again once I'm out of the warranty I will be following one of those DIYs to tighten that connection.

If its something as simple as pulling the IC and popping a hose back on, I'd rather handle it by myself, and get it on tighter since it seems to be an issue. I've only got 3300 miles on it, so I'm sure its going to come up again. I'd also like to get to know my car under the hood a little better.
I'm getting anxious to get home so i can start tinkering!

From what I understand there's a funky coupler involved that is a P.O.S. Basically I think people have eliminated the coupler and used a better clamp to get the hose on the TB/IC directly.

Sure enough, the hose blew off of the TB! Pretty easy fix... But of course it couldn't be the IC side of the hose. I'm going to look into a better fix.. But for now its drivable.
I hope i didn't suck too much junk into the engine, but i only drive it about a mile so i don't think i should be worried.
